// QUICK DOCUMENTATION
//
//				(see also the full documentation at http://sigslot.sourceforge.net/)
//
//		#define switches
//			SIGSLOT_PURE_ISO			- Define this to force ISO C++ compliance. This also disables
//										  all of the thread safety support on platforms where it is
//										  available.
//
//			SIGSLOT_USE_POSIX_THREADS	- Force use of Posix threads when using a C++ compiler other than
//										  gcc on a platform that supports Posix threads. (When using gcc,
//										  this is the default - use SIGSLOT_PURE_ISO to disable this if
//										  necessary)
//
//			SIGSLOT_DEFAULT_MT_POLICY	- Where thread support is enabled, this defaults to multi_threaded_global.
//										  Otherwise, the default is single_threaded. #define this yourself to
//										  override the default. In pure ISO mode, anything other than
//										  single_threaded will cause a compiler error.
//
//		PLATFORM NOTES
//
//			Win32						- On Win32, the WIN32 symbol must be #defined. Most mainstream
//										  compilers do this by default, but you may need to define it
//										  yourself if your build environment is less standard. This causes
//										  the Win32 thread support to be compiled in and used automatically.
//
//			Unix/Linux/BSD, etc.		- If you're using gcc, it is assumed that you have Posix threads
//										  available, so they are used automatically. You can override this
//										  (as under Windows) with the SIGSLOT_PURE_ISO switch. If you're using
//										  something other than gcc but still want to use Posix threads, you
//										  need to #define SIGSLOT_USE_POSIX_THREADS.
//
//			ISO C++						- If none of the supported platforms are detected, or if
//										  SIGSLOT_PURE_ISO is defined, all multithreading support is turned off,
//										  along with any code that might cause a pure ISO C++ environment to
//										  complain. Before you ask, gcc -ansi -pedantic won't compile this
//										  library, but gcc -ansi is fine. Pedantic mode seems to throw a lot of
//										  errors that aren't really there. If you feel like investigating this,
//										  please contact the author.
//
//
//		THREADING MODES
//
//			single_threaded				- Your program is assumed to be single threaded from the point of view
//										  of signal/slot usage (i.e. all objects using signals and slots are
//										  created and destroyed from a single thread). Behaviour if objects are
//										  destroyed concurrently is undefined (i.e. you'll get the occasional
//										  segmentation fault/memory exception).
//
//			multi_threaded_global		- Your program is assumed to be multi threaded. Objects using signals and
//										  slots can be safely created and destroyed from any thread, even when
//										  connections exist. In multi_threaded_global mode, this is achieved by a
//										  single global mutex (actually a critical section on Windows because they
//										  are faster). This option uses less OS resources, but results in more
//										  opportunities for contention, possibly resulting in more context switches
//										  than are strictly necessary.
//
//			multi_threaded_local		- Behaviour in this mode is essentially the same as multi_threaded_global,
//										  except that each signal, and each object that inherits has_slots, all
//										  have their own mutex/critical section. In practice, this means that
//										  mutex collisions (and hence context switches) only happen if they are
//										  absolutely essential. However, on some platforms, creating a lot of
//										  mutexes can slow down the whole OS, so use this option with care.
//
//		USING THE LIBRARY
//
//			See the full documentation at http://sigslot.sourceforge.net/
//
//
// Libjingle specific:
// This file has been modified such that has_slots and signalx do not have to be
// using the same threading requirements. E.g. it is possible to connect a
// has_slots<single_threaded> and signal0<multi_threaded_local> or
// has_slots<multi_threaded_local> and signal0<single_threaded>.
// If has_slots is single threaded the user must ensure that it is not trying
// to connect or disconnect to signalx concurrently or data race may occur.
// If signalx is single threaded the user must ensure that disconnect, connect
// or signal is not happening concurrently or data race may occur.
